This is an example project that demonstrates the usage of Protocol Buffers in Go. It includes a sample .proto file defining the data structures and a main Go program that showcases serialization, deserialization, and saving data to binary and JSON files.

Before running the code, make sure you have the following dependencies installed:

• Go (https://golang.org/doc/install)
• Protocol Buffers Compiler (protoc) - Make sure it is in your system's PATH (https://developers.google.com/protocol-buffers)

1. Clone this repository or copy the .proto file and the main Go program to your project directory.

2. Generate Go code from the .proto file by running the following command:

   protoc --go_out=. --go-grpc_out=. employess.proto
   

   This will generate the necessary Go code for the defined data structures.

3. Update the import paths in the Go program to match your project's structure. Replace import "proto_example/example/proto" with the appropriate import path for your project.

The main program (main.go) demonstrates the following:

1. Creating instances of the Employee and Employees data structures defined in the .proto file.

2. Serializing the Employees instance to binary data using the gp.Marshal function.

3. Deserializing the binary data back into a new Employees instance using the gp.Unmarshal function.

4. Saving the binary data to a file named "Binary".

5. Creating a JSON representation of the deserialized Employees object using json.Marshal.

6. Saving the JSON data to a file named "output.json".

To run the code, execute the following command in your terminal:

go run main.go

The program will output the following:

• The binary data representation of the serialized Employees object.

• The deserialized Employees object.

• The message "Data saved to file." indicating that the binary data has been saved to a file named "Binary".

• The message "JSON data saved to file." indicating that the JSON representation has been saved to a file named "output.json".

Make sure to inspect the generated binary and JSON files after running the program.

Feel free to modify the code or the .proto file to suit your needs and explore further possibilities with Protocol Buffers in Go.
